Primary Retinal Detachment

3 Encircling Operation with Drainage for Primary Retinal Detachment
vitrectomy. Both procedures share the complications of penetrating
ocular injury.
After careful examination, a skillfully executed encircling and
drainage operation has a high rate of success. However, morbidity
leads to a gradual change in the author’s practice. Encircling and
drainage are not necessary conditions for a high rate of first operation
success after scleral buckling; in fact, one can be equally successful
employing less-morbid procedures. An editorial concluded
that “accurate localization of all retinal holes and precise placing of
the buckle are of course essential, and confidence in the success of
the procedure is necessary to outweigh a fear of failure induced
in the surgeon by the presence of fluid under the retina at the end
of the operation. The temptation to drain and ‘make sure’ must be
resisted.Yielding may well court complications” [43].
